Abstract
The utility model discloses an oil path oil injection structure for a lubricating system, which comprises an oil path pipeline for forming an oil path channel, wherein one end of the oil path pipeline is connected with an upstream interface, the other end of the oil path pipeline is provided with an oil injection port, the cross section area of the oil path from the inner side to an outlet of the oil injection port is gradually reduced, and the outer side of the oil path outlet of the oil injection port is provided with an expansion port with a suddenly enlarged cross section area. The other end of the oil pipeline is provided with an oil nozzle, the cross section area of the oil pipeline from the inner side to the outlet of the oil nozzle is gradually reduced to increase the pipeline pressure of lubricating oil, the outer side of the oil outlet of the oil pipeline of the oil nozzle is provided with an expansion port with the suddenly enlarged cross section area, and the oil pressurized in the pipeline is rapidly sprayed out of the oil nozzle and is rapidly dispersed under the action of the expansion port. The oil nozzle structure forms spiral air flows on two sides of the high-speed oil beam, so that air and engine oil are fully mixed to form oil mist. The oil mist can lubricate the various moving parts.
Description
Technical Field
The utility model relates to an oil path oil injection structure for a lubricating system.
Background
At present, corresponding lubricating pipelines need to be arranged in an internal combustion engine, the existing lubricating pipelines are single in structure and generally only serve as lubricating oil channels, the functions are single, and the lubricating effect on cam chambers in the engine is poor.
Disclosure of Invention
The utility model provides an oil path oil injection structure for a lubricating system, which can fully lubricate the internal structure of an engine, and aims to solve the problems of single function and poor lubricating effect of the oil path of the existing engine lubricating system in use.
The technical scheme for solving the existing problems is as follows: the oil path oil injection structure for the lubricating system comprises an oil path pipeline for forming an oil path passage, wherein one end of the oil path pipeline is connected with an upstream interface as an improvement, an oil injection port is arranged at the other end of the oil path pipeline, the cross-sectional area of an oil path from the inner side to an outlet of the oil injection port is gradually reduced, and an expansion port with a suddenly enlarged cross-sectional area is arranged on the outer side of the oil path outlet of the oil injection port.
As a further improvement, the cross-sectional area of the minimum position of the oil path pipeline is S1, the cross-sectional area of the oil path at the minimum position of the oil spray nozzle is S2, and the cross-sectional area of the oil path at the expansion port of the oil spray nozzle is S3, so that S1/S2 is more than 1.5; S3/S2 is greater than 1.8.
As a further improvement, a one-way valve which is communicated with the oil injection port in a one-way mode is arranged in the oil line.
Compared with the prior art, the oil spray nozzle is arranged at the other end of the oil pipeline, the cross section area of the oil pipeline from the inner side to the outlet of the oil spray nozzle is gradually reduced to increase the pipeline pressure of lubricating oil, the outer side of the outlet of the oil pipeline of the oil spray nozzle is provided with an expansion opening with the suddenly enlarged cross section area, and the oil pressurized in the pipeline is sprayed out from the oil spray nozzle at high speed and is quickly dispersed under the action of the expansion opening. The oil spray nozzle structure has the beneficial effects that spiral air flows are formed at two sides of the high-speed oil beam, so that air and engine oil are fully mixed to form oil mist. The oil mist can lubricate the various moving parts.

Fig. 2 is a view of the lubrication system housing of the present invention.
Fig. 3 is a cross-sectional view of an oil jet of the oil line of the present invention.
Detailed Description
Referring to fig. 1-3, in this embodiment, an oil path oil injection structure for a lubrication system includes an oil path pipeline 1 for forming an oil path passage, one end of the oil path pipeline 1 is connected to an upstream connector, an oil injection port 2 is disposed at the other end of the oil path pipeline 1, a cross-sectional area of an oil path from an inner side to an outlet of the oil injection port 2 is gradually reduced, and an expansion port 3, of which the cross-sectional area is suddenly enlarged, is disposed at an outer side of an oil path outlet of the oil injection port 2.
For further elucidation of the utility model, the oil line 1 may be arranged in a crankcase in general, the oil injection opening 2 may be arranged in a cam chamber, the crankcase may be provided with an oil reservoir communicating with the upstream end of the oil line 1, and the oil injection opening 2 at the other end of the oil line 1 is directed towards or arranged in the cam chamber. When lubrication is required, the cross-sectional area of the oil path from the inside of the oil jet 2 to the outlet is gradually reduced, which increases the injection pressure of the oil jet 2. referring to fig. 3, the pressurized oil jet 2 forms spiral air flows on both sides of the high-speed oil jet, so that air and engine oil are sufficiently mixed to form oil mist. The floating oil mist can effectively lubricate each moving part and can enter the upper rocker arm chamber along with the air flow, so that parts in the upper rocker arm chamber can be fully lubricated.
In order to achieve an effective oil mist spraying effect, the minimum cross-sectional area of the oil path pipeline 1 is S1, the minimum cross-sectional area of the oil path of the oil spray port 2 is S2, the cross-sectional area of the oil path of the expansion port 3 of the oil spray port 2 is S3, and S1/S2 is more than 1.5; S3/S2 is greater than 1.8.
The oil pipeline 1 can also be provided with a one-way valve which is communicated with the oil injection port 2 in a one-way.
